First Lady hopeful Melania Trump moved the crowd at the Republican National Convention with a heartfelt speech on Monday night. Now, she's moving Twitter amid suggestions she may have borrowed from another first lady.

Early Tuesday, Donald Trump's campaign commented on the speech in a statement that notably avoids mention of the controversy.

"In writing her beautiful speech, Melania's team of writers took notes on her life's inspirations, and in some instances included fragments that reflected her own thinking. Melania's immigrant experience and love for America shone through in her speech, which made it such a success," wrote Jason Miller, Trump's senior communications adviser.

Paul Manafort, the Trump campaign chair, also defended the authenticity of the speech, saying the themes Melania touched on were universal.

"We're talking about words like compassion, love of family, respect," Manafort told CBS. "These are not words that are unique words, that belong to the Obamas."

Melania or someone tweeting on her behalf also took to Twitter to defend her speech. Notably, they omitted the #FamousMelaniaTrumpQuotes hashtag.
